The appearance of visual defects on parts such as cracking, crazing, grooves, ripples, wave marks, and flaky brittleness often indicates more than an aesthetic problem.
What to Do About Weak Weld Lines
Weld or knit lines are perhaps the most common and difficult injection molding defect to eliminate.
Sticking Sprues or Parts? Lots of Possible Causes and Solutions

How to Stop Flash
Flashing of a part can occur for several reasons—from variations in the process or material to tooling trouble.
What You Can Learn from Shot Profiles
Want to know more about your molding process? Need a better way to diagnose problems? There's no better tool than the electronic 'signature' provided by process-monitoring curves of cavity pressure and other variables. Here's a sampling of seven rea...
